TORCH-LAMP.

SPECIFICATION forming part of Letters Patent No. 316,440, dated April28, 1885. Application filed April 30, 1884. (Xo modell) To a/ZZ whom itmay concern:

Be it known that I, CHARLES L. Bnfrrs, a citizen of the United States,residing in Chicago, in the county of Cook and State of Illinois, haveinvented a new and useful Improvement inTorch-Lamps, of which thefollowing is a specification. Y

In the present invention the lamp reservoir or bowl is made of glass,and is provided n ear its top or above its center of gravity with a beador groove, on or in which tits a metal band or ring to which thesupporting-frame is pivoted, either directly or indirectly, through asecondary swivel-ring or gimbals, when it is desired that the lamp shallbe permitted to incline in both directions to the pole or staff of thetorch.

Another feature of the invention consists in providing this bead orgroove with notches or depressions for the ends of the pivots upon whichthe lamp swivels or turns, and also for the ends of the wireiguards,which are made to pass through or partially embrace the band or ringwhich lies in or over the bead or groove. It will be of convenience toconstruct the glass lamp with a neck having a cup-shaped flange orextension to serve as a drip-cup to catch any oil which may flow downfrom the wick. The neck itself may be also made long enough to afford afirm bearing and tight joint for a removable wick-tube, so that nocement or packing will be necessary. A cork, rubber, or other elasticsleeve may, however, with better results surround the wickstube. Thewick-tube should be made long enough to extend to near the bottom of theglass reservoir, so as to envelop or inclose the whole length of thewick, by which means the wick can be readily inserted through the neckwithout danger of dripping the oil therefrom. The tube should beprovided with perforations to admit the oil to the wick.

In the accompanying drawings, which form a part of this specification,and in which similar letters of reference indicate like parts, Figure 1is a perspective view of a device embodying my invention. Fig. 2 is atopor plan view of the same. Fig. 3 is a cross-section on line 3 3 of Fig.2. Fig. 4 is a side elevation of the glass reservoir with the frame'andband removed, and Fig. 5 is a side elevation showing a slightmodification. Fig. G shows a modification wherein the notches to receivethe ends of the guards are formed in the band, instead of the glass.

In said drawings, A represents the reservoir or oil-receptacle of thelamp, which is made of glass or similar material. B is a band or ring,which is rigidly secured to the glass lamp-reservoir A by means of thebead or 6o projection a, raised on the body of the glass reservoir nearits top, or at least above its center of gravity, over which bead saidband fits. The band or ring, when made of sheet metal, is provided withinturned flanges b b at its top and bottom edges to iit over the bead,and thus secure the band in place. If the band or ring B is made ofwire, as shown in Fig. 5, it tits in the groove a. The band B is pivotedto a secondary ring, C, by the pins or rivets b b', and the ring C is inturn pivoted to the yoke or supporting-arms D, so that the lamp mayincline in either direction to the torchst-aff or pole E, the pivots b bstanding at right angles to the yoke or frame 7 5 D. The arms D are madeof stiff wire, and are soldered at their lower ends to the polesocket F.The socket is made of sheet'metal, and should be provided withlongitudinal grooves f, to receive the wiresD, so as to give 8o strengthand rigidity to the frame.`

The glass reservoir A is provided with notches or depressions at in thebead or groove to receive the ends or heads of the pivots b', andsimilar notches, a, for the ends ofthe guardwires G. These notches ordepressions, in connection with the pivots b, or the guards G, fittingin said notches, also serve to keep theband or ring in place and preventits slipping or rotating on the reser 9o voir A. The guard-wires G maybe four or more in number, and the diametrically-opposite guards maypreferably be made continuous in one piece of wire. The guards G are allsoldered together at thepoint Q,where they cross each other. The endsofthe guards G have a short hook or bend, g', at their ends, which areinserted between the ring or band B and the glass reservointhe sameresting in the sockets or notches a3 provided for them.

The ring B, if made of sheet. metal., as shown in Figs. l, 2, 3, and 4,should have holes b2,

v the guards G are formed in the groove a.

' proj ect. Otherwise the hooks may simply parthe ring B is made ofwire, it may preferably through which the ends of the hooks g may ltially embrace the ring, as shown in Fig. 5.

H represents the wick-tube or burner. It is made of sheet metal, and isprovided with perforations h. It ts within the glass neck a* of the lampA, which neck is made long enough to afford apractically-tight joint;but a cork, rubber, or other sleeve, a5, may be inserted between thetube and neck. The neck a4 is provided with a cup-shaped Iiange, a6, atits top, which will serve to catch any oil that may exude from the wick.The wick-tube I-I has a bead, 7L', which fits down on top of the necka4, and serves to make the joint tight.

In the modifications shown in Fig. 5,where be composed. of two separatepieces of wire, the endsof which are twisted at diametricallyoppositepoints, so that the twisted portions is pivotally connected with theframe D or the intermediate ring, C. The latter, however, in Fig. 5 isomitted. In Fig. 5 it will also be observed that the notches ordepressions a? for I desire it be understood that in the specificationand claims the bead a and groove a,as a means of securing the ring B tothe glass reservoir A, are considered as equivalents of each other, andmy invention includes either a raised or a depressed corrugation forsecuring the band to the glass reservoir.

W'here a sheet-metal ring having inturned flanges b is used,a notch ordepression should be made in the glass reservoir where the ends of thering unite, so that the same may be soldered together without the soldertouching the glass.

By making the oil-reservoir A of glass in this manner a much'cheaper aswell tas better torch-lamp is produced than where the reservoir is madeof tin or sheet metal, and there is no danger of a glass reservoirleaking.

Instead of forming the notches a3 for the guards G in the glass as anequivalent construction, these notches may be made in the ring B.

I claiml. In a torch-lamp, the combination of a glass oil-reservoir, A,provided with a corrugation, with a ring, B, secured to said reservoirby said corrugation, and frame D, pivoted to said ring, substantially asspecified.

2. The combination,with glass reservoir A, provided'with a bead orgroove near its top having notches or depressions therein, of a ring, B,secured to said reservoir, and guards G, tting in said notches andsecured to said reservoir by said ring B, substantially asspech fied.

3. The combination of glass reservoir A, pro` vided withacorrugation,with ring B, secured to said reservoir by said corrugation,an intermediate ring,C, pivoted to said. ring B,and 6 5 frame D, pivotedto said ring C, and provided' with socket F, substantially as specified.

4. The combination, withglass reservoir A, having a corrugation providedwith notches or depressions therein, of a ring, B, ring G, having pivotsb b tting in said notches, and frame D, pivoted to said ring C,substantially as speciiied.
